FDA Panel Votes Down Pacira sNDA for Pain Blocker
FDA’s Anesthetic and Analgesic Drug Products Advisory Committee has voted 6 to 4 to not recommend approval of a Pacira Pharmaceuticals supplemental NDA for Exparel (bupivacaine liposome injectable suspension) and its use as a nerve block to produce regional analgesia. The six panel members agreed that more research data are needed to further support the proposed indication. The user fee review action target date is 4/6. Exparel is currently indicated for infiltration into the surgical site to produce postsurgical analgesia.
The company says the submission is based on data from a Phase 3 study of Exparel in femoral nerve block for total knee arthroplasty and a Phase 3 study in brachial plexus block for shoulder surgeries. It also includes data from eight company-sponsored studies with safety and pharmacokinetic data through 120 hours, and data from two investigator-initiated studies that provide additional experience in smaller, peripheral nerve block settings.
